Pacquiao hasnt been a natural 130 pounder for awhile now, he was coming at 140-144 over the past year or two, and thats a lot of weight for a super featherweight to put on, more than Corrales put on against MAyweather I believe. Pacquiao was having a ton of difficulty making the weight for the last year and halfish. Even at lightweight he came in at 147 which means he is probably naturally around 160 pounds judging by his weight gain. Pacquiao brings certain things that Oscar has never delt with, particularly how Manny moves in and out so quickly, and its quite hard to Manny with any punch either than the right hand consistently which I think Oscar can do, but is his right hand hard enouhg to hurt Pacquiao? He wasn't able to hurt Forbes or Floyd with it, we will see if he can against Manny, because I don't see him landing that left hook a whole lot, I could be wrong ,but watching Manny's fights I see he has been very elusive to the left hook over the past few years.
